CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención está relacionada con la industria de la construcción en lo general; en lo particular se relaciona con aditivos incorporados en concretos de alta resistencia para prefabricados, asi como para concretos permeables que les brinda mejores propiedades físicas. The present invention is related to the construction industry in general; In particular, it relates to additives incorporated in high-strength concrete for prefabricated materials, as well as permeable concrete that gives them better physical properties.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Dentro de la industria de los concretos permeables, es cada vez más importante construir pisos y pavimentos que puedan ser tomados en cuenta para los diseños arquitectónicos, los cuales son cada vez más demandantes en lo que a las características de textura, color y forma se refiere; además de considerar la posibilidad del uso de piezas prefabricadas. De la misma forma dentro de la industria de la construcción en general, es cada vez más importante construir estructuras cada vez más ligeras y que puedan utilizarse a mucha mayor velocidad y tanto los prefabricados como los pre-esforzados han sido desarrollados para resolver este problema; sin embargo, los diseños arquitectónicos
actuales son cada vez más demandantes en lo que a las características estructurales se refiere, en una buena medida debido a que los claros son cada vez mayores, lo cual provoca que las dimensiones de las piezas prefabricadas sean también mayores y mucho más pesadas, generando la necesidad de usar equipos muy grandes, tanto para su transportación, como para su instalación, generando la necesidad, cada vez mayor, de utilizar elementos y materiales que permitan construir pieza más ligeras, con el incon eniente de que todo esto se convierte en importantes aumentos a los costos de producción de las piezas. Within the permeable concrete industry, it is increasingly important to build floors and pavements that can be taken into account for architectural designs, which are increasingly demanding in terms of texture, color and shape characteristics. ; In addition to considering the possibility of using prefabricated parts. In the same way within the construction industry in general, it is increasingly important to build increasingly lighter structures that can be used at a much faster speed and both prefabricated and pre-stressed structures have been developed to solve this problem; however, architectural designs current are increasingly demanding in terms of structural characteristics, to a good extent because the clearances are increasing, which causes the dimensions of the prefabricated parts are also larger and much heavier, generating the The need to use very large equipment, both for transportation, and for its installation, generating the need, increasingly, to use elements and materials that allow the construction of lighter parts, with the unaware that all this becomes significant increases to the production costs of the pieces.
En el estado de la técnica se ubicó la patente Mexicana MX 217475 otorgada el 10 de noviembre de 2003 de Jaime Grau Genesias et al la cual protege un material constructivo filtrante para pisos, pétreo, de diferentes granulometrías controladas, que se aglutina con polímeros para formar una mezcla homogénea que, después de cierto tiempo, adquiere dureza y permeabilidad hasta de un 90%, y que es susceptible de ser vaciado en moldes para darle una forma específica, y que presenta como características preponderantes del producto podemos resaltar su resistencia al intemperismo, alta resistencia a la compresión, alta resistencia a la flexión, resistencia a la abrasión, moldeabilidad, no es combustible, no es contaminante y variabilidad de densidades y aplicaciones. El material puede ser fabricado en bloques de diversa densidad y tamaño, en medidas estandarizadas, o bien, de aplicarse en obra a manera de concreto para pisos, permitiendo por su alta capacidad
filtrante recuperación de líquidos en altísimos porcentajes, de manera que habilitado en calles o zonas normalmente cubiertas por pavimentos o asfaltos, permite que el terreno siga cumpliendo su función filtrante natural, sin alterar la recuperación de agua para los mantos freáticos de las ciudades. In the state of the art, the Mexican MX 217475 patent issued on November 10, 2003 by Jaime Grau Genesias et al., Which protects a filtering construction material for floors, stone, of different controlled granulometries, which is bonded with polymers to form a homogeneous mixture that, after a certain time, acquires hardness and permeability up to 90%, and that is capable of being emptied into molds to give it a specific shape, and that presents as preponderant characteristics of the product we can highlight its resistance to weathering, High compressive strength, high flexural strength, abrasion resistance, moldability, non-combustible, non-polluting and variability of densities and applications. The material can be manufactured in blocks of different density and size, in standardized measures, or, to be applied on site as concrete floors, allowing for its high capacity filter recovery of liquids in very high percentages, so that enabled in streets or areas normally covered by pavements or asphalts, it allows the land to continue fulfilling its natural filtering function, without altering the recovery of water for the water tables of the cities.
También se ubicó la patente MX 270135 B otorgada el 07 de septiembre de 2009 de Néstor de Buen-Unna et al, la cual se refiere a un aditivo para la elaboración de concretos ecológicos permeables con alta resistencia a la compresión, flexión y abrasión, que permita la filtración del agua hacia el subsuelo, que puede ser mezclado con cualquier tipo de cemento, agua y cualquier agregado duro para dar como resultado un concreto de gran resistencia, de larga durabilidad hecho a base de agentes dispersantes, agentes de enlace, humectantes, hidroxipropiletil celulosa o hidroxipropilmetil celulosa y silico aluminatos y opcionalmente agua, agentes surfactantes, agentes bactericidas y antiespumantes. Sin embargo esta composición es muy distinta de la nueva invención desarrollada y de características menos avanzadas que no brinda las mismas ventajas fiscas que se exponen a los largo de los objetivos y de la descripción. Por lo que toca a los concretos permeables existentes en el mercado, estos han demostrado que casi nunca funcionan a la
perfección, presentando importantes desgranamientos y muy poca capacidad de carga; los únicos que han demostrado dar como resultado concretos permeables de buenas características presentan algunas deficiencias, entre las cuales podemos mencionar: The MX 270135 B patent issued on September 7, 2009 of Nestor de Buen-Unna et al., Which refers to an additive for the preparation of permeable ecological concretes with high resistance to compression, bending and abrasion, was placed. allow the filtration of water into the subsoil, which can be mixed with any type of cement, water and any hard aggregate to result in a high-strength, long-lasting concrete made from dispersing agents, bonding agents, humectants, hydroxypropylethyl cellulose or hydroxypropylmethyl cellulose and silico aluminates and optionally water, surfactants, bactericidal agents and antifoams. However, this composition is very different from the new invention developed and with less advanced features that does not provide the same tax advantages that are exposed to the objectives and the description. As regards the permeable concrete existing in the market, these have shown that they almost never work at perfection, presenting important shreds and very little load capacity; the only ones that have proven to result in permeable concrete of good characteristics have some deficiencies, among which we can mention:
> Presentan ciertas dificultades en el manejo de las mezclas. > They present certain difficulties in the handling of the mixtures.
Resulta totalmente inútil incluirlos en los camiones mezcladores en las plantas de premezclado cuando estas se encuentran a más de 25 minutos de distancia del sitio de la obra. It is totally useless to include them in mixer trucks at ready-mix plants when they are more than 25 minutes away from the construction site.
> Enorme dificultad al usarlos en climas con temperaturas muy altas. > Huge difficulty when using them in climates with very high temperatures.
> No es recomendable enviar más de 4 m3 dentro de los camiones de premezclado (ollas). > It is not advisable to send more than 4 m 3 inside the ready-mix trucks (pots).
> El material se queda pegado en las ollas o trompos (camiones de premezclado), generando pérdidas en la mezcla y la necesidad de sacarlas de circulación (a las ollas o trompos) para limpiar los tanques. > The material remains stuck in the pots or tops (ready-mix trucks), generating losses in the mixture and the need to remove them from circulation (to the pots or tops) to clean the tanks.
> Las juntas constructivas presentan desprendimientos después de algunas semanas, particularmente las "juntas frías". > Construction joints show detachments after a few weeks, particularly "cold joints".
> El tiempo durante el cual se puede instalar la mezcla es muy corto . > The time during which the mixture can be installed is very short.
> Las mezclas resultantes son difíciles de manejar y se requiere de un proceso de entrenamiento para manipularlas adecuadamente.
Por otro lado, dentro del mercado de los prefabricados y pre esforzados los aditivos existentes no resuelven el problema relacionado al peso y tamaño de las piezas. En la actualidad hay una gran cantidad de empresas que fabrican aditivos para las más diversas aplicaciones, pero ninguno de ellos ha demostrado poder ser aplicado para los casos como los de la presente invención . Después de múltiples pruebas tanto en campo como en el laboratorio, una gran inversión de personal y recursos, fue que se llegó al desarrollo de la presente invención. > The resulting mixtures are difficult to handle and a training process is required to handle them properly. On the other hand, within the prefabricated and pre-stressed market the existing additives do not solve the problem related to the weight and size of the pieces. At present there are a large number of companies that manufacture additives for the most diverse applications, but none of them has proven to be applicable for cases such as those of the present invention. After multiple tests both in the field and in the laboratory, a great investment of personnel and resources was that the development of the present invention was reached.
La invención que ahora presentamos soluciona, en el caso de los concretos ecológicos permeables, todos los problemas arriba mencionados, logrando además, para el caso de los prefabricados y los pre-esforzados, piezas más ligeras, manejables, de mejor resistencia y más económicas.
